A config option by default will automatically be added as a system property
with its name as the suffix. In this case, the property will be
"zookeeper.tcpKeepAlive", when the zoo.cfg file is parsed. See
QuorumPeerConfig.java for more details. So this doc should be updated.
Having it as a system property is actually better as we can query the
property when we need it, instead of change the signatures of various classes
and pass it around.
